Zoall whont it may concern.-

Be it known that I HERBERT LEE- BUGG, a citizen of the United States,residing at Walnutridge, in the county of Lawrence and State ofArkansas, have invented a new and useful Acetylene-Gas Generator, ofwhichthe following is a specification.

My invention relates to certain improvementsin acetylene-gas generators;and it consists principally in improved construction of the mechanismfor supporting and; removing the carbid vessel from the generator, asmore fully set forth hereinafter.

In the accompanying drawings, Figure 1' is a vertical central sectionalview of an acetylene-gas-generatingapparatus constructed in Fig. .2 is adetail sectional view of the same, taken on line a a of Fig. 1. Fig. 3is a detail perspective view of the generating vessel.

The water-tank 1 is provided with a false bottom 2, whereby acompartment 3 is formed in the bottom of the water-tank. The bell 4,forming the gas-holder, is provided with laterally-extending lugs orears 5, having openings through which extend guide-rods (3, that projectVertically from the sides of the watertank. The gas holder orbell has achamber 7, which depends centrally from the top 'of the bell, the bottomof the said chamber being closed and provided with an opening 8 and-theupper end'of the said chamber being open. A cylindrical generatingvessel 9 is placed in the chamber 7 and is of slightly less diameterthan said chamber, the said generating vessel having its upper endclosed and provided with a vent-cock 10 and handle 11 and the lower'endof said chamber'or'generat ing vessel 9 being open,as shown. A U -shapedstrap 12 of suitable material has the upper end of its vertical armspivoted to the sides of the vessel 9, the said strapbeing adapted toswing under the-bottom of the said ,vessel and support the same in aslightly-elevated position above the bottom of the chamber 7 and thesaid strap also serving to support the cylindrical carbid vessel 13,which is placed in the vessel 9, so that when the latter is lifted outof the chamber 7 the said carbid vessel will be lifted with said vessel9. The swinging strap also serves as a means for readily detaching thecarbid vessel from the generating vessel 9 after they are removed fromthe apparatus. The bottom 14 of the cylindrical carbid vessel is at somedistance above the lower edge of the same, thereby forming a compartment15, under the bottomot the carbid vessel, which compartment 15 is openon its lower side and has communicating openings 16 in the sides of thecarbid vessel The latter is provided with suitable openings 17 above thebottom thereof, and at the upper end of the carbid vessel, which isopen, is a bail-or handle 19, by means of which the carbid vessel may bereadily handled when the same is out of the generating vessel 9. A tube19 is disposed verticallyin the carbid vessel, extends from a suitabledistance above the upper end thereof downward to the bottom of the'same,and the said tube 19 is adapted to slide vertically on a gas-pipe 20,which leads from the compartment 3 in the bottom of the water-tank, theupper and lower ends of said gas pipe being open. A gas-pipe 21 alsoextends vertically from the bottom of the water-tank and communicateswith the compartment 3, and said pipe 21 has a check-valve 22 at itsupper end, which is disposed in the gas-space within the bell. Agas-service pipe 23 is provided, which communicates with the gas-spacein the bell and preferably extends down through the waterspace in thewater-tank and may be provided.

with a suitable valve, as at 2ft. A tube 25, which is closed atitsrupper end and open at its lower end and provided at asnitabletdistance from its lower end with openings 26, is disposedvertically in and carried by the bell. A gas-discharge pipe 27 has itsupper end disposed in said tube 25, and said gas-discharge pipe leads tothe open air exterior of the building in which the gas-generatingapparatus is installed. 7

In operation, the tank 1 being supplied with water, the carbid vesselbeing charged-with carbid, and the parts being assembled as shown inFig.1 and hereinbefore'described, the water from the tank 1 enters thelower end of the chamber 7 through the opening 8 and forms a sealbetween said chamber 7, the generating vessel 9, and the carbid vessel,the air below the bottom of the latter being vented through the openings16, and as the Water enters the opening 17 it attacks the carbid,thereby causing acetylene gas to be generated. As the gas increases involume it passes from the generating chamber or vessel 9, through thepipe 20, into the chamber 3 in the bottom of the tank, from saidchamber, through thepipe 21, past the check-valve 1 22 into the bell,and from the latter through submerged in the water in the tank, where'upon the excess of the gas will be discharged through the pipe 27, andhence danger of explosion is averted.

' The excess of water in the newly-generated gas condenses in thereceptacle 3, and the water of condensation may be drawn from saidreceptacle when necessary through a waste pipe 28, which is providedwith a trap 29 and stop-cock 30.

Having thus described my invention, I claim The combination in anacetylene-gas generator, of the water-tank 1, a bell 4 having acentrally-disposed open-top cylinder 7, a perforated bottom for saidcylinder, an openbottom generating vessel 9 situated within saidcylinder and having a handle 11, a U- shaped strap 12 having its endspivotally connected to the opposite sides of the vessel and resting onthe perforated bottom of the cylinder and supporting said vessel at adistance above said bottom, a carbid vessel in said generating vessel,said carbid vessel being supported on said strap and removable with thegenerating vessel from the apparatus, said strap serving as a means forreadily decaching .the carbid vessel from the generating-chamber,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

HERBERT LEE BUGG.
